This section of the Handbook deals with the culture of the Andean region between Ecuador and the northern border of Aymara territory as it was observed by the Spanish conquerors in the 16th century and recorded in surviving documents. This area includes the whole of the desert Coast of Perti and the broken valleys of the Peruvian Highlands, a region which was the home of many different tribes, ...

Multidrug-resistant Salmonella enterica serovar Typhimurium (S. Typhimurium) isolates with four different antimicrobial resistance patterns obtained from a beef cattle farm were characterized to determine their clonality. Macrorestriction analysis of genomic DNA revealed that these four isolates are closely related to each other and can be classified as a newly emerged pulsed-field gel electrop...

A new version of the Integrated Nitrogen in Catchments model (INCA) was developed and tested using flow and streamwater nitrate concentration data collected from the River Kennet during 1998. INCA is a process-based model of the nitrogen cycle in the plant/soil and instream systems. The model simulates the nitrogen export from different land-use types within a river system, and the in-stream ni...

Large multidrug resistance plasmids of the A/C incompatibility complex (IncA/C) have been found in a diverse group of Gram-negative commensal and pathogenic bacteria. We present three completed sequences from IncA/C plasmids that originated from Escherichia coli (cattle) and Salmonella enterica serovar Newport (human) and that carry the cephamycinase gene blaCMY-2. These large plasmids (148 to ...

Cirrus clouds play an important role in the earth’s energy balance. To quantify their impact, information is needed on their microstructure and more precisely on the number and size of the ice crystals. With the anthropogenic activity, more and more aerosol particles and water vapor are released even at the altitude where cirrus clouds are formed. Cirrus clouds formed in a polluted air mass may...

Saturn’s largest moon, Titan, provides an interesting opportunity to study how dense atmospheres interact with the surrounding plasma environment. Without an intrinsic magnetic field, this satellite’s nitrogen-rich atmosphere is relatively unprotected from plasma interactions. Therefore, the energydeposition rate is important for understanding chemistry and dynamics in Titan’s atmosphere. Since...

The genomic island SGI1 and its variants, the important vehicles of multi-resistance in Salmonella strains, are integrative elements mobilized exclusively by the conjugative IncA/C plasmids. Integration and excision of the island are carried out by the SGI1-encoded site-specific recombinase Int and the recombination directionality factor Xis. Chromosomal integration ensures the stable maintenan...

El presente artículo explicará cómo los canales de regadío ayudaron a cierta población en «La achirana del inca», texto que forma parte las Tradiciones peruanas, obra escrita por Ricardo Palma. En esta tradición se cuenta el inca Pachacutec, amor una joven, ayuda vivía un desierto Ica y les construye canal fue terminado diez días. Este ayudaría habitantes ese lugar la producción sus sembríos te...
